(a) Performance Evidence

Evidence required to demonstrate competency in this unit must be relevant to and satisfies all of the requirements of the elements and performance criteria under the specified conditions of assessment, and must include:

• The preparation and termination of electrical cables to aircraft industry standards, using crimping techniques, soldering techniques and solder sleeves joints.

• The correct interpretation of aircraft wire markings, terminal block identification and plug/socket pin numbering systems.

• Inspection of electrical looms and harness pre and post-removal and installation to ensure minimum bends are maintained, cable is not in tension, plugs are correctly aligned, security of route ensures no chaffing of insulation, adequate clipping and cable ties have been utilized and construction complies with aircraft industry standards.

• Positive identification of miscellaneous electrical hardware and/or components in all aircraft systems.

(b) Knowledge Evidence

Evidence required to demonstrate competency in this unit must be relevant to and satisfy all of the requirements of the elements and performance criteria and include knowledge of:

• Component attachment methods.

• Connection of hardware and plugs.

• Application of relevant WHS practices.

• The use of approved maintenance documentation and aircraft publications relating to miscellaneous aircraft electrical hardware and components.

• Electrical wiring used in aircraft and wire marking.

• Plug/socket pin numbering and terminal block identification.

• Cable and loom installation requirements.

• Crimping tools and crimp terminals.

• Soldering techniques and the use of solder sleeve joints.

• Electrical fundamentals.

This field allows for different work environments and conditions that may affect performance. Essential operating conditions that may be present (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) are included. 

Hardware connection methods include:     

• Bolted. 

• Soldered. 

• Plug connectors. 

Types of electrical hardware include:     

• Switches, relays, lamps, terminal blocks, current limiters, circuit breakers, fuses, sockets, potentiometers, capacitors, inductors, magnetic amplifiers, transformers, rheostats, resistors and diodes, miscellaneous sensors and minor components hard mounted throughout the aircraft, busbars, lugs, ferrules, splices, connectors and electrical, electronic cables and looms.

Basic soldering and crimping:     

• The work will include the application of basic soldering and crimping skills associated with removal and installation of electrical hardware. 

Procedures and requirements include:     

• Industry standard procedures specified by manufacturers, regulatory authorities or the enterprise.

• The assessment are compose of paper exams , interviews, and practical demonstrations, which the paper exam is the main testing. The selection of interviews and practical demonstrations are depending on the assessors’ judgment.

• Competency should be assessed in the workplace or simulated workplace using tools and equipment specified in maintenance manuals. It is also expected that general-purpose tools, test and ground support equipment found in most routine maintenance situations would be used where appropriate.

• An understanding of the attachment methods, connection of hardware and system operation as they relate to the work must be demonstrated before undertaking any action. The work plan should take account of applicable safety and quality requirements in accordance with the industry and regulatory standards.

• It is essential that applicable cleanliness requirements and WHS safety precautions are fully observed, including awareness of electrostatic discharge procedures.

• Evidence of transferability of skills and knowledge related to removal and installation is essential.

• A person cannot be assessed as competent until it can be demonstrated to the satisfaction of the workplace assessor that the relevant elements and performance criteria are being achieved under routine supervision on each of the connection methods:

• Bolted.

• Soldered.

• Plug connectors.

• This shall be established via the records in the Log of Industrial Experience and Achievement or, where appropriate, an equivalent Industry Evidence Guide (for details refer to the Companion Volume Implementation Guide).
